THIS IS NOT MY ANSWER i got this from someone else but i think this will help u cause it’s from the same question:

We have our initial unit of speed: 343 m/s.

We want to find how many kilometers sound will travel when the air is at 68 degrees in five seconds.

Step 1: Multiply 343 by five. (1 sec. to 5 secs.)
343 * 5 = 1715

Step 2: Divide 1715 by 1000. (1 m. to 0.001 km)
1715/1000 = 1.715 km/5 secs.

At a temperature of 68°, sound will travel 1.715 km in 5 seconds.

What are the end points of the triangle called? How are they labeled?
horrorfan [7]

For this case we have that by definition:

A triangle is defined by three lines that are called sides, or by three points called vertices.

We know that:

  1. <em>The vertices of a triangle are labeled with capital letters. </em>
  2. <em>The sides of a triangle are written with lowercase letters. </em>
  3. <em>The angles of a triangle are written similarly to the vertices. </em>

Answer:

The end points of the triangle are called vertices.

They are labeled in capital letters.
